Key Compatibility

Installation

To install this lock simply insert the ball into the coupler's ball socket. Insert the collar into the base plate until it's snug against your trailer latch and the holes align with the holes in the base plate. Insert the lock through the holes in the base plate, and use your vehicle's ignition key to secure it.


When you insert your own key into the cylinder, spring-loaded plate tumblers move up and down until they are matched exactly to that key. The first time the key is rotated, the cylinder is uniquely coded to that key. When the key is removed, the cylinder moves into the locked position. When the key is turned again, it will rotate to the unlocked position.

Using on my Aluma car trailer. Fits well and instructions well written. Can even combine with latch pin for added security. Uses my Toyota truck tailgate key as advertised.

I still like all of the Bolt products and am still using them. I would say that I do not recommend the Bolt padlocks as while they have the same great key setup I think the shackle is too long, too thin, and too exposed for easy removal by a small grinder or bolt cutter. Otherwise great stuff. I do wish they actually made a hockey puck style padlock instead

by:
Took forever but given current international complications, it’s understandable . Thanks for your constant updates.
by:
Ordered it and received it in two days, Outstanding, everything worked as expected. I now have the 5 padlocks, receiver lock, and trailer coupler lock all set up using my ignition key, I love the fact I don't have to use 7 different keys and always have the key with the truck. Great stuff.

great, no problem

by:
One of the better locks available for a decent price. Easy on and off, requires a cutoff wheel to defeat. I liked it enough to buy a second one.... thus, I can put two hoops on one red base and be even more secure.

Was really happy to get this "off hitch" coupler lock along with a locking receiver pin and an "on hitch" coupler lock that are now all 3 keyed the same as my ignition key for my pulling vehicle. Put your key in and turn it to the right and you are done. Should have sought this solution a long time ago.

Great Product. I never have to hunt the key because it is keyed to my GMC Canyon ignition key.

I just bought this item and I can't say how much of a great product this is! From ordering, to having a video to show you how to assemble and then demonstrate on how to use it properly was a big plus! And finally it's made in America!!

Glad you are liking it, Joshua! The BOLT locks definitely make these things a lot more convenient! ^___^ What kind of trailer are you using this on?

by:
It is made out of strong steel which would be difficult to cut through. While no product is 100% theft proof, this seems much better than average. I really like that it is keyed to my truck key. There are already too many keys for my trailer, so using a key I already have is convenient.

We've tried a TON of different coupler locks for our 2019 Jayco RV with an underslung coupler, and we ended up having to send them all back because they're too narrow. A year or two ago, after giving up on all the other brands from all the other sellers, I got on the phone with an e-trailer rep, and he dug through the available options to find one wide enough, and this one works!

Since it's keyed to the tow vehicle key, and since we sold our previous tow vehicle, I just bought another one because I KNEW it would fit, and it does. So thankful for this lock and for etrailer's help.

Excellent quality! Superior security! I have Bolt products on boat trailer and cargo trailer. The feature that all my Bolt products are all keyed to my ignition key sure comes in handy!

Works great with my 2026 GMC Sierra. I always have the key for the lock with me.
by:
Good news is that it works like all B.O.L.T. locks I have with one key. Bad news is that there is no way to seat the cylinder COMPLETELY against the hitch, which leaves a small gap that a thief could get a hacksaw into. Still, the pros outweigh the cons.
